====== sys03 - ilog-policy ======
{{tag>project infrastruktur computing process }}

On sys03 and the VServers shackspace runs [[http://www.fischglas.de/software/ilog/|ilog]]
for system and software documentation. [[http://www.fischglas.de/software/ilog/ilog-quick-usage-guide/|ilog quick usage guide]].

===== How to document? =====

Write down what you actually did - not what you thought you were doing.

Write down commands, filenames with full path names, include current 
working directories, diff(1)s of changed files.

**Don't:**
  * Just write something like "cleaned up /var/log", "set up xyz" or something - because nobody knows **how** you did it. If there's an error we are all blind and deaf and lost in the mists of Avalon.

**Do:**
  * If you make a change to a config file add the diff to the ilog entry.
  * Use "vo" on editing files.
  * Write down the commands you used
  * check the output of "history" if you write the ilog record
  * consider typing commands into an editor first and transferring them to shell copy & paste. So you create a protocol which can be used as ilog record afterwards.

===== ilog keywords =====

The keywords ilog uses are defined as following:

^ keyword  ^ host                                                  ^ vserver                                                                                                   ^
